Mask Filtration Efficiency/Airflow Resistance Tester is suitable for testing the filtration efficiency of protective masks and various breathable materials/films, etc. It is widely used by equipment manufacturers, testing institutions, and research organizations.
This instrument is a combined product of the following two instruments; customers can purchase either one individually.
Mask filter material airflow resistance and breathing machine resistance test. (Mask filter material airflow resistance tester can be purchased separately.)
2. Mask Filter Material Filtration Efficiency Test (Particulate Matter Filtration Efficiency) (Mask Filter Material Filtration Efficiency Tester can be purchased separately)
Product Features
We do not engage in hyping up face masks or non-woven fabrics. Our company supplies at actual prices, stabilizing market prices.
High-precision multi-functional laser particulate matter sensor
High-precision airflow pressure gauge
Equipped with an aerosol generator
All-stainless steel work surface, easy to clean. Rust-free, ensures cleanliness.
The testing mold is made of 304 stainless steel, which will not cause any other contamination and affect the measurement results.
Multiple sample fixtures for various test areas (optional)
Continuous aerosol particle generator, large capacity, rapid refilling (optional or self-purchased)
Test gas flow range adaptable to various testing standards (adjustable as required)
Test mold with integrated (mask air flow resistance/filter efficiency) testing function (standard configuration)
High-precision air flow and pressure regulators ensure the accuracy of test data.
No touch screen or computer is used due to the uncertainty in counting dust particles. Refer to the actual display of a dust particle counter for guidance.
Testing Items
NaCl particle filter efficiency/air particle filtration
Distribute NaCl particles according to standard flow and concentration requirements, and detect the remaining NaCl particle content in the filtered gas sample.
Oil particle filter efficiency
Perform exhalation and inhalation resistance tests, measure air flow pressure, calculate pressure differences (mask air flow resistance), etc. (Optional)
